ASUS A55vm/K55vm cant boot up after bios update. Please Help

Hello guys,
I am in trouble here, 2days ago I decided to update my windows from 7 to 8.1, clean install. No problem there, then I download this bios from Asus, dlcdnet.asus.com/pub/ASUS/nb/K55VM/K55VMAS211.zip , I updated it using WinFlash from Asus, the WinFlash said its the right bios, after I load optimized default at bios menu, the laptop restarted and wont boot.

What I've tried so far :
-I already tried to reset the CMOS battery (by unplugged it)
-Bios recovery procedure based on ,forums.mydigitallife.net/threads/870-Bios-Recovery-Procedures , Iam using CD and Flash disk to boot the drive. There's no respond at all when using Flash disk, there's some activity when using CD but it stop after 10-15s. I can't really find the right bios/bios name to doing Boot Block recovery, i already tried to rename it to amiboot.rom but nothing happened (im not really sure its the right file/bios)

If there's someone who had same problem and fixed it, or anyone who can help, please help me
Thanks in advance, sorry for my bad english
